FGUR-HOBSE DOUBLETREE To all whom it may concern:

Be it known that 1, CHARLES A. BRADLEY, of Haviland, in the county ofKiowa and State of Kansas, have invented a new and Improved Four-HorseDoubletree, of which the following is a specification.

My invention has for its object to provide a simple and inexpensiveconstruction of double tree particularly adapted for four horses and itgenerically comprehends such arrangement and cooperative connection ofthe main or draft beam and the double trees that the said trees are heldsufficiently far from the wagon wheels as to miss them in turning and atthe same time give plenty of room for the sawing of the horses.

My invention also consists in certain details of construction andpeculiar combination of parts, all of which will be hereinafter fullyexplained, specifically pointed out in the appended claims andillustrated in the accompanying drawings, in which Figure 1, is aperspective view of my invention. Fig. 2, is a transverse sectionthereof on the line 22 of Fig. 1. Fig. 3, 1s a detail view of the partsthat constitute the main or draft bar, and Fig. 4, is a similar view ofone of the double trees and its inner or yoke member.

Referring now to the drawings, 1 designates the main or equalizer barthat consists of a long fiat metal member 1 0 and a shorter member 11that has its opposite ends bent inwardly at approximately right anglesto form foot portions 12 that are riveted to the upper side of the bar10, as clearly shown in Fig. 1 which also shows the said member 11 bentupwardly to form upper and lower strap bars ab, so that the device canbe readily fulcrumed onto the tongue or the wagon pole.

4 designates the double trees, each of which consists of a pair of metalbars held spaced. apart at the ends by the spools 40 and rivets 41, theouter spool and rivet forming the fulcruming means for a swingle treehook 5, mounted in the outer end of the tree and so shaped that it maybe quickly connected with the swingle tree.

At the inner ends the trees 4: have a U- shaped member 6 connectedthereto, the inner part of which is of sufficient length to straddle thepart 2 and to limit the outward Specification of Letters Patent.

pull and the inner portion of the tree as clearly understood from thedrawing, which also shows the front ends 60 of the member 6 extended andapertured as at 61, for receiving the swingle tree. In the outer ends ofthe double tree members are pivotally mounted U-shaped hooks pivotallyconnected at one end in such manner that they can be readily turnedoutwardly in the horizontal plane for reasons presently explained.

By reason of constructing the parts as hereinbefore described. andshown, the use of the general form of clevises is avoided, which is agreat advantage since no time is lost in searching for them, and furtherit enables hitching the horses closer to the wagon than otherwise can bedone, and further since the hooks 5 when turned out allow the outsidehorse to be unhitched; and. loops to which the inside horses are joinedwill not allow the horses to pull ahead far enough so that the tonguewill come down. This advantage is especially valuable in places when itis necessary to take off the outside horses in order to enable theinside horses to draw the wagon into the elevator.

The outside device in practice being of metal and joined by the rivetsas shown, rough weather or usage cannot affect the parts as there is notimber to warp or to screw the clevis on.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

1. A draft appliance of the character described, that comprises ametallic main bar, another bar mounted centrally thereon and spacedtherefrom to form an upper member, tubular rivets mounted between themain and upper bars, a double tree comprising a pair of parallel bars,fulcrumed on each end of the member, a hook rotatably mounted at one endof the said parallel bars, and a U- shaped strap secured on the otherend of the parallel bar, said strap straddling the main ar, for thepurposes described.

2. The hereinbefore described improvement in draft appliances of thecharacter stated, comprising in combination, a long flat metal bar,another bar having down turned ends that form foot portions fitted andsecured on the fiat metal bar, a double tree pivotally mounted on eachend of the members straddling the main bar, for the long berg1 af hookgotatablly mollllntedi in the purposes stated.
